Learning objective
Understand the types of friction and their nature.
Learn to calculate static and kinetic friction forces.
Know how elastic forces arise and their kinds (normal force, tension).
Write the equations of motion on an inclined plane and calculate its efficiency.
Expected outcomes
Determines whether a body stays at rest or slides by comparing with the maximum static friction.
Calculates the acceleration, the friction angle and the efficiency of an inclined plane.
Explains ways of reducing and increasing friction with technical examples.
